----------------------------------
Summary: Conflict resolution should utilise Merkle trees to improve
performance
Key: ISPN-8412
URL:
https://issues.jboss.org/browse/ISPN-8412
Project: Infinispan
Issue Type: Enhancement
Components: Core
Affects Versions: 9.2.0.Alpha1
Reporter: Ryan Emerson
Assignee: Ryan Emerson
Currently we detect conflicts between CacheEntry replicas by retrieving all entries for a
cache segment and comparing their values on the node initiating the conflict resolution.
This does not scale. Instead, we should generate a Merkle tree for each segment on the
replica nodes. When initiating conflict resolution, it is then possible to retrieve a
segments hash from each of its owners and determine if a conflict is present before
requesting the conflicting entries.
